ive tried 2 different plug caps and leads along with 2 brand new spark plugs.
how can i have power at the coil and yet no spark at the plug?

If there is an intermittent supply to the LT side of the coil (your fluctuating test light) the coil will not energise. Same applies if the voltage is too low, or there is insufficient current flow (bad connections etc.) You really need to test the LT supply voltage with a multimeter and the LT earth resistance with a multimeter.
